Why This Matters Across Episodes
The longer arc this connection carries
The Doctor leaves Xeros with an artifact that becomes crucial in Episode 30. The Visualiser's repair and use to reveal the Daleks’ plans is a direct consequence of its earlier acquisition, establishing both causal and thematic continuity between the episodes.
